The term theroelectric is a combination of two words thermo and electric and as the name implies thermal means heat energy and electric means electrical energy. Thermoelectric generators are the tools used temperature difference between two nodes in electrical energy. A operation of thermoelectric generator is based on Seebeck effect. According to which a loop of two dissimilar metals develops an emf when the two compounds at different temperatures. That is why it is also referred to as Seebeck Power Generation. A thermoelectric generator consists essentially of heat source, which is at high temperature and a heat sink, which at a temperature lower than the heat source is maintained. The temperature difference between the heat source and heat sink in direct current through the load flow. In such energy conversion there is no intermediate energy conversion as with most of the conversion as it is also called direct energy conversion. The energy generated as a result of Seebeck power generation is single phase DC and given by I2RL or VI when RL is the load resistance.
The output voltage and output power increased by increasing the temperature difference between the hot and cold ends or by multiple thermoelectric generators in series. The current will continue to flow as long as heat is fed to the hot junction and removed from the cold junction. This flow by thermo or Seebeck power generation DC in nature and can be converted into alternating current invertors and stress can increase further by transformers. The conversion of energy by means of thermo-electric or Seebeck power generation is reversible process i.e. the direction of the energy flow can be reversed. If we remove the tax and deliver direct current on the clamps where the load is connected, the heat can be easily pulled from the thermoelectric generator is a combination of two words thermo and electric and as the name implies thermal means heat energy and electric means electrical energy.

Consider a thermoelectric power generator having heat source at one end and heat sink at other end. The heat source is kept at high temperature as compare to heat sink. Let the temperature difference between two junctions is ΔT. The sides of generating device are insulated so, the heat flows along the length only. The applied heat to the hot junction causes the electrons in the n type block and the holes in the p type block to flow away from the heat junction and thereby producing a electrical potential difference. The circuit is completed by connecting a load resistance, RL. The current will start flowing through this load resistance
